This is really cool! I like the moody ambience created by the dreary scenery and especially the sound design. The last leg of the game also got me pretty tense, which I certainly wasn't expecting going in. If I had to pick out one thing I would've liked to see, it would be more sections that did something with the idea that your character stops when they hit a checkpoint; there were only a couple points where this really mattered, with most of the game being more focused around timing your jumps. Other than that though, this was a pretty well put together experience!
